[Setup] The Accuser and the Mountain

[Not Known 15]

This setup is very close to 11:2 Mountainous(slightly scumsided by EV), but it has two features: One to remove a loophole(not very interesting) and one (hopefully interesting) feature that will allow the town to overcome the mountain. I also used a much stronger and town controlled variant in the other, smaller setup I have been publishing:

The Accuser and the Mountain

11 Vanilla Townies

2 Mafia Goons

Feature 1: The town is investigating the activities of the Mafia. The kill of the Mafia is compulsive.(no-killing to force town to lynch at MLYO is prohibited)

Feature 2: The Accuser and the Judgement:

On Day 1, the Town will decide on who to lynch, but the Day 1 target will be forced to drink a poison that will kill them on Day 2. They will become the Accuser. The Accuser cannot be killed on Night 1.
On Night 1, the Accuser will select two primary suspects and two secondary suspects; if they are town.
Day 2 will have 2 phases: The Accusation Phase and the normal lynch phase.
Judgement Phase:
If the Accuser is

mafia

, the game moderator will announce

The Accuser has destroyed evidence. They were a member of the

Mafia

!

. Then the Accusation Phase ends, and the normal lynch phase begins.

Otherwise, the game moderator announces:

The Accuser has selected [name 1] and [name 2] as the primary suspects and [name 3] and [name 4] as the secondary suspects!

From then on until the Accusation Phase deadline the Accuser may make their Final Decision on who is, in their eyes, the mafia team(2 suspects,

including at least one primary suspect

)
During the Accusation Phase everyone may try to convince the Accuser of their version, and the Accuser may ask questions.

Final Decision: When the Accuser makes their final decision they will post the names of two suspects, at least one of them must be a primary suspect.
Then the Moderator will announce:

The accusation did not match the evidence! The Accuser has succumbed to the poison. They were a member of the

Town

!
The lynch phase begins.

(Or, for the unlikely event that the accusation is correct, the game ends).

The rest of the game is played normally.

Mountainous EV is fine it's just town sucks

I think this would work better as a micro with power roles. It's an interesting mechanic, but it doesn't feel like it'd be at all fun to play (especially if that mechanic happens literally once). The sole effect of the mechanic is ruling out a singular potential scumteam.
